Finding initial key of Fibonacci LFSR knowing only polynomial and output stream-cipher

rs flag

I need to know whether it is possible to find the initial key of a Fibonacci LFSR knowing only length and taps and output stream-cipher bit sequence?

Plaintext is not ASCII, nor some other sort of printable characters. It's also a bit sequence.

LFSR: 15bit $X^{15}+X^{14}+1$

Is this homework (or another type of learning exercise)?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
